Debuginfod cache use index cache settings and include real file name (#120814)

This PR include two changes:
1. Change debuginfod cache file name to include origin file name, the
new file name would be something like:

llvmcache-13267c5f5d2e3df472c133c8efa45fb3331ef1ea-liblzma.so.5.2.2.debuginfo.dwp
So it will provide more information in image list instead of a plain
llvmcache-123
2. Switch debuginfod cache to use lldb index cache settings. Currently
we don't have proper settings for setting the cache path or the cache
expiration time for debuginfod cache. We want to use the lldb index
cache settings, as they make sense to be in the same place and have the
same TTL.

The LLVM Compiler Infrastructure

OpenSSF Scorecard OpenSSF Best Practices libc++

Welcome to the LLVM project!

This repository contains the source code for LLVM, a toolkit for the construction of highly optimized compilers, optimizers, and run-time environments.

The LLVM project has multiple components. The core of the project is itself called “LLVM”. This contains all of the tools, libraries, and header files needed to process intermediate representations and convert them into object files. Tools include an assembler, disassembler, bitcode analyzer, and bitcode optimizer.

C-like languages use the Clang frontend. This component compiles C, C++, Objective-C, and Objective-C++ code into LLVM bitcode -- and from there into object files, using LLVM.

Other components include: the libc++ C++ standard library, the LLD linker, and more.

Getting the Source Code and Building LLVM
